In my experience, there are reasons to check for a NULL pointer other than dereferencing it. A common memory-leak idiom is reallocating storage and assigning its address to a pointer that already points to allocated storage. The correct idiom is to only allocate storage if the pointer is currently NULL. But nowhere in that particular idiom would a NULL pointer necessarily be referenced. https://www.brotherprintersupportnumber.com/blog/how-to-fix-printer-keeps-going-offline-error/, should you have any questions or comments, please let me know.

Predator and CL could not provide any possible suspects. Using Code Search for the file, "ports/event.cc" suspecting the below Cl might have caused this issue Suspect CL: https://chromium.googlesource.com/chromium/src/+/0db0bcf5fb39232fc705cc34b4c617ec463f0092 rockot@ -- Could you please check whether this is caused with respect to your change, if not please help us in assigning it to the right owner. Thanks!
